Google Penalizing "Scraper" Sites

From

The Weekly Feed #55

Google launched and update that may radically affect the amount of search engine traffic your blog or website gets. They're calling it a minor update to their algorithm, but it has already had a major effect on some sites. 8 Days ago I mentioned on Hacker News that a site that was scraping the popular StackOverflow was ranking higher than them - by republishing their content. Well Google has updated their algorithm and the scraper site's traffic immediatelyplummeted by about 90%. The day-over-day drop is 40%. I'm not a fan of sites that steal content, but ouch!!
